摘要：A mixed reality system including a head-mounted display (HMD) and a basestation. Information collected by HMD sensors may be transmitted to the base via awired or wireless connection. On the base, a rendering engine renders frames including

virtual content based in part on the sensor information, and an encoder compresses theframes according to an encoding protocol before sending the frames to the HMD overthe connection. Instead of using a previous frame to estimate motion vectors in theencoder, motion vectors from the HMD and the rendering engine are input to theencoder and used in compressing the frame. The motion vectors may be embedded inthe data stream along with the encoded frame data and transmitted to the HMD overthe connection. If a frame is not received at the HMD, the HMD may synthesize a framefrom a previous frame using the motion vectors.
